We all live in a society obsessed by brand names and the latest gadget. Sometimes with reason sometimes with none.The RPI has one major problem with audio. The clocks coming from CPU can only output one frequency clock perfect (very close), resulting in major problems with audio files sampled at 44Khz (and multiple). Too much jitter on i2s clocks. So we...
A Capacitance Multiplier is designed to make a small capacitor function like a capacitor that is much, much larger. This design reduces the output ripple/noise of any PSU to almost negligible levels (less than 5mV up to 1Mhz).
Add the Cheapo with S/PDIF Shield to your Sparky SBC for added functionality!
Every SBC has a crystal that it used to send digital signals to your DACs. The accuracy of this crystal is very important in how well the DAC will transform the digital signal into analog sounds. Simply put: a better crystal means a better sound! Most SBCs use a very cheap crystal with lots of jitter in order to save costs.
There are many DACs for RPI Zero. Most of them low-priced, carbon copy of datasheet, slave DACs. We decided to do something different
Piano can work as a 2.0 (all frequencies are passed to LR) as a 2.2 (xover frequency is chosen in GUI) and subwoofer has 2 outputs or as a 2.1 (same as 2.2 but subwoofer is mono).
Our PIANO Hi-Fi DAC Shield has been designed for those seeking audio perfection. Every detail has been thought of! First we start with 4 LDOs, one & two for the analog (avcc), the third for the digital (dvcc) and the fourth for the headphone amplifier.
We had this power adapter made to specifications guaranteeing the lowest ripple and noise possible. This helps in the quest to achieve the highest possible sound quality. Includes interchangeable wall plug heads for US, EU and UK.
